Substantial country house, C16, recased and remodelled inside in 1834-6 by T.H. Wyatt, now nunnery. On site of a Cistercian Abbey dissolved in 1536, the mansion was built after William Morgan of Pentrebach bought the abbey lands in 1554, he was MP and High Sheriff, and died 1582. His son Edward (1548-1633), also MP and High Sheriff, was notable as one of the most principled Catholics of the period, fined repeatedly for this. He may have been the builder as a 1588 date was noted on the house in 1799. His son Sir Edward, first baronet, supported the Catholic cause, was a noted Royalist in the Civil War and died in 1653. His son Sir Edward, 2nd baronet, (died 1682 ), also a Catholic, gave shelter to Saint David Lewis (1616-79), the Jesuit priest burnt at Usk. From 1682 through the C18 the house was intermittently occupied, descending to two sisters, Mrs Blewitt and Mrs Fettiplace, and thence to Reginald John Blewitt. It was in decay in 1799 when Coxe saw it and noted a 1588 date on the porch. Blewitt (1790-1878) rebuilt the mansion in 1834-6, recasing the exterior in Bath stone in a Tudor to Jacobean style, and remodelling the interior. He was a barrister, founder of the Monmouthshire Merlin 1829, the Monmouth and Glamorgan Bank 1837, Mayor of Newport 1837-8 and MP 1837-51, but his renovation of the house costing supposedly £60,000 and the collapse of the bank in 1851 led to his exile abroad 1851-68. There were additions for Blewitt, presumably before 1851, probably the dining-room and the very large octagonal conservatory (demolished c. 1946). The estate went into chancery for many years. Offered for sale 1888, when owned by a nephew, Mr Downing, who sold it in 1895 to Sir Clifford Cory, chairman of the Cardiff coal owners and exporters, Cory Bros. & Co., MP for St Ives, High Sheriff 1905. Cory added the block of marble-lined bathrooms off the stair hall. After his death in 1941 used as an American Army depot. Bought by the Sisters of St Joseph of Annecy in 1946, as their British headquarters, or Provincialate, replacing a house on Stow Hill, Newport used since 1873. The house was restored, a new chapel built 1957 on the site of the conservatory, the stable block was rebuilt as 2 storeys in 1950, a wing to the right of the front was added 1968, and an Infirmary Wing to the rear in 1982. The architects after 1950 were F.R. Bates, Son & Price.
This is the principal early work of T.H. Wyatt (1807-80) eminent Victorian architect, RIBA President 1870 and Gold Medallist 1873, exhibited at the Royal Academy, 1835, and the pre-eminent Welsh example of the early C19 Tudor to Jacobean revival, comparable for example with Salvin's Mamhead, Devon of 1826 and Rickman's Matfen Hall, Northumberland, 1832.
The site of the Cistercian Abbey is not known, presumed to be under the house. It was founded from Strata Florida by Hywel ap Iorwerth of Caerleon in 1179 and initially known as Caerleon Abbey. The Elizabethan house was of the same basic plan as the present one with wing projecting to right, battlement, with mullioned windows.
